This 34 years old had backache. An MRI (images not available) showed spine and sternal lesions. The CT scan showed the eccentric vertebral lesions that are easy to biopsy, but the sternal lesion is easier and allows even more tissue to be obtained. Also while the spine lesions seem to be due to an infection like tuberculosis, the sternal lesion is unusual and may be the better lesion to biopsy from that perspective as well.

Using an 18G coaxial biopsy gun, I biopsied the sternal lesion using an oblique approach.

The diagnosis was tuberculosis.
